topological, he believes that they could form the basis for fault-tolerant quantum computers. On a
fundamental level, he says that spin-3/2 fermions provide a very rich spectrum of possible
pairing
configurations for physicists to study
– adding that their work has already garnered significant
interest from other physicists.
Indeed, an important fundamental question, says Paglione, is how the spin-3/2 fermions pair up in
the first place. “What’s the glue that holds these pairs together?” he asks. “There are some ideas of
what might be happening, but fundamental questions remain
– which makes it even more
fascinating.”
